IMPROVEMENT `IN STRETCHERS FOR PAINTINGS.

Specification forming part -of Letters Patent No. 112,435, dated March'7, 18-71.

` 'Be it known that I, JAMES FAIRMAN, of New l York city, in the countyand State of N ew York, 3 `have invented a new and Improved Stretcherfor Paintings; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had totheaccompanying drawing, formy ling part of this specification.

Figure l represents a detail face view, show- 1n g one corner of astretcher with my improve ment. Fig. 21sa detail edgeview of the miterand separating-wedge. Fig. 3 is a face view Similar letters of referenceindicate 'corresponding parts.

The object of this. invention is to improve l. the construction andarrangement lof the l stretcher-frames for oil-paintings.

The sections which compose the stretchers now in use are at presentjointed atl the cora ners by tenons and mortises, and can be spread bywedges, which are forced between the adjoinin g edges. The constructionof the sections `with such tenons and mortises is ex- 1, pensive, anddoes not produce reliable articles,

` ,f as the wood is considerably weakened therey the latter deficiency,and also Y 3 reduce the expense of making the stretchers,

fby. i To obviate I employ a metallic connecting-plate, which a entersthe slotted or groovedmitered 'endsof two adjoining 'sections of theframe, holding the same properly together. This isaid conprojecting ribon one face, which, entering transverse grooves, l prevents the sectionsfrom slipping apart. I

which is intermitered ends of Vsections--as,

frame, tostraddle the joining-plate and force the sections'apart.

A B in the drawing represent portions of the adjoining sections of astretcher-frame. They are mitered, to lit together atthe corners, andhave their mitered ends grooved for the reception of the joining-plateC. This plate is made of metal, of suicientlength and width, and entersthe grooves of the adjoining sections, as shown.

From one face ofthe plate C projects a transverse rib,'a, enteringcorresponding grooves in the sections, and serving to prevent thesections from beingspread apart. Such rib may be provided, if desired,on each side ofthe plate.

D is a wedge, forked as shown in Fig. 2. It is applied between thesections A B, so as to straddle the plate C, and separates the sectionsto the desired extent. j

a `The' same invention-that is to say, the joining-plate G,.l1aving therib a and the forked wedge-may be arranged between other than forexample, in the middle of each side of the stretcher.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- 1. The joining-plate C, provided with the rib a, andapplied to a stretcher, substantially' as herein shown and described.

2. The forked wedge I), combined with the joining-plate (l, to straddlethe same when spreading the stretcher, as specified.

JAMES FAIRMAN,
